I'm converting to jupyter from sagenb, and am having trouble finding equivalent interface shortcuts for a couple of features. (a) In sagenb, to get a new cell I can hit a +/wordballoon icon. In jupyter, do I have to go through the pulldown menu or is there some way to get a new cell by mousing inside the notebook? (b) In sagenb, there is a wysiwyg interface for the explanatory-text cells. In jupyter, I'm not finding one; I seem to have to code everything manually in markdown.

Am I missing something, or are those time-saving features gone?

Also: One feature I wanted that was not present in sagenb was the ability to delete output cells. (This is so I can make a lab notebook for a class without having to make a test copy and then copy/paste all the input cells to a fresh notebook.) Is that possible somehow in jupyter? I see that I can hide output cells, but it's not exactly the same.

Agreed that some of these things should be in Jupyter - and aren't.

In Jupyter, the keyboard shortcut to create a new cell is Esc (to enable the command mode) and then

  • A for a new cell above the current one
  • B for a new cell below the current one

To get the list of all shortcuts, click on Help --> Keyboard Shortcuts in the menu bar.

Regarding the text cells, there is indeed no wysiwyg interface and you have to use markdown (or html code). Note that markdown is very easy to learn. Moreover you can use LaTeX for formulas.

To delete output cells, use Cell --> All Output --> Clear from the menu bar.
